NPRR621 Counter-Party Specific Calculations for M1 Variable
ReasonThe existing Protocol methodology for computing Mass Transition risk does not reflect the market risk profile. The time required for Mass Transition will differ greatly depending on the number of Electric Service Identifiers (ESI IDs) held by a Counter-Party. In addition, Counter-Parties with neither Load nor Generation will not have transition risk.

Summary
This Nodal Protocol Revision Request (NPRR) replaces the fixed value for M1 with a calculation that will be specific to each Counter-Party. This revision defines M1 as the minimum of the existing value of 20 and the sum of two components: · M1a -- Time period required to cover any termination event · M1b -- Time period to cover Mass Transitions onlyThe M1a component is applicable to all Counter-Parties. However, the M1b component will be applicable only to Counter-Parties with Load or generation.
